The Spire name is one that's going to be familiar to enthusiast PC folk, so the Spire Gemini Rev. 2 ought to have some serious cooling chops to back up its not inconsiderable girth.

We've seen a lot of CPU coolers sitting in the £40 bracket recently. All of them claim superior cooling performance across a wide range of stupidly powerful (and hot) processors and finger-shredding socket configurations.

One of the best we've seen in the last few months was Enermax's first try at CPU cooling with its catchily-titled ETS-T40-TA.

We're still not entirely sure what the marketing team was doing while the engineers were coming up with one of the finest, most bargainous coolers we've tested.

So Spire has a lot of work to do with the Spire Gemini Rev. 2 and a lot of competition to keep in check.

With a dual-fan, push-me-pull-you setup, manual fan-speed controller and six copper heatpipes it certainly seems like it means business.

Gemini Rev.2 is the Zodiac sign for the twins. We have codenamed our newest high-end thermal solution due to the two towering dimpled fin heat-sinks. Gemini is the ultimate evolution of the hugely successful TherMax cpu cooler series. The increased number of heat-pipes combined with a higher number and density of dimpled fins and crowned with two (2) high airflow fans for extreme cooling performance. Six (6) U-shaped 6mm heat-pipes are in contact through the solid copper base with the CPU, rapid heat transfer to the 52 aluminum dimpled fins providing a larger surface area for optimum heat dissipation. The Gemini Rev.2 is supplied with two (2) 12cm balanced DC fans providing high airflow and sufficient cooling. Compatibility is guaranteed with multi-platform mounting for all current Intel and AMD micro-processors. The Gemini is pure cooling power that takes performance to the level.
